The concept of using guide pins to load large fixtures has been around for a long time, and it even applies when incorporating Unilock zero-point clamping systems in your fixturing.
The main Unilock clamping knob is very robust, i.e.: very hard, and as such it can cause damage to a Unilock chuck if a fixture is very heavy or large.
Guide pins are set up on the base, and their corresponding holes or notches located on the edge of the fixture pre-position the fixture so, that as it is being lowered, the knobs do not impact the critical location faces of the clamping chuck.
This also has the added benefit of keeping operators in a safe location not having to use their hands & fingers to fine-adjust a slightly out-of-place fixture being lowered.
